摘要
简要介绍了DMT(离散多音频 )技术 ,在此基础上详细阐述了用于HFC(光纤混合同轴电缆 )网络上行信道数据传输的SDMT(同步多载波调制 )系统的原理 ,分析了其性能。得到的结论是 :与采用单载波系统进行比较 ,SDMT具有更大的优越性 ,它是用于接入网HFC上行信道传输的一个较先进的解决方案。
This article gives a brief introduction of the technology of DMT, and particularly illustrates how to use SDMT theory to transmit data in HFC network up channel, then makes an analysis of SDMT system's performance.The conclusion is: SDMT system has an advantage over the single carrier system and is considered to be an advanced solution used in access network.
